After huge hail and wind damage across Deep South on Saturday, further rounds of heavy weather and flood cuts will target these areas and expand eastward toward Monday.
Two separate storm currents pushing northeast across the Deep South and Tennessee River Valley can cause severe weather to be clustered in two specific areas.
"The first cluster of severe weather is expected to push through South Texas and threaten communities from Laredo to McAllen and Corpus Christi on Sunday morning," AccuWeather Senior Meteorologist Kristina Pydynowski said.
These storms will move northeast northeast like an intense squall line this afternoon, rumbling through Houston and Baton Rouge, Louisiana, before sunset.
More isolated storms can fire both in front and behind this organized line across the lower Mississippi Valley and eastern Texas.
"The Second Area of Seven It is possible to light the weather around Little Rock and Memphis on Sunday morning before pushing north over parts of Tennessee and the Ohio River valleys for the rest of the day," Pydynowski added.
These storms are likely to lose some of their intensity at the time they come to Nashville, Tennessee, and Louisville, Kentucky, on Sunday afternoon, but will still be able to produce short, powerful downsides and strong winds.

The biggest threats from all rounds of severe weather will be harmful wind, hail and flood.
There may also be isolated tornadoes, especially in connection with storms in Texas and Louisiana.
By Sunday evening, the severe breathing will change east into Mississippi and eastern Louisiana and return to western Tennessee.
"The severe weather risk after dark will make it important for residents to keep their cell phones on and charge with audible severe weather alerts enabled all night," according to AccuWeather Meteorologist Renee Duff.
"Motorists along stretches of interstates 10, 20, 30, 35, 49, and 55 may face sudden reductions in visibility and an increased risk of hydroplaning during transport at highway speeds," according to Pydynowski.
When the soil becomes saturated due to the repetitive downpours, the wind blows low as 40 to 50 mph may suffice to knock down trees and power lines.
Gases of 60 to 70 mph will be possible in the most intense storms and wind of this magnitude can cause damage to property and transform loose objects into dangerous projectiles.

By Monday, the threat to heavy, stormy storms and repetitive downturns will shift east to the southeast and the Carolinas. 
Although the threat to severe weather will be less severe than Sunday's, a few cases of wind and hail damage cannot be ruled out.
But the biggest threat from the storms this Monday will be a river flood triggered by heavy precipitation in a short time.
Floods of low-lying and poor drainage areas as well as small currents and streams are likely.
In areas hit by the hardest downs, streits and roadways can be temporarily immersed by larger rivers that leave their banks.
Motorists should avoid flooded roads. It only takes 1 to 2 feet of moving water to make most vehicles stop or get swept away.
In addition, the prolonged period of wet, stormy weather will only worsen and worsen the ongoing flood problems on the Mississippi River and its tributaries.
On Monday night, the highest rainfall of 3 to 6 inches is expected to extend from eastern Texas and western Louisiana in southeastern Arkansas, northern Mississippi, and western parts of the Tennessee Valley.
In these areas, an AccuWeather Local StormMax ™ of 10 inches will be possible.
Outside these ranges, rainfalls of 1 to 3 inches will be most common.
Although dry weather is expected to return during the middle of the week, weather patterns will remain favorable for several rounds of thunderstorms and heavy rainfall over at least the third week of April.
